The occurrence of 4-Chloro-N-[(4-methyl-5-{[(4-nitrophenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methyl]benzene-1-sulfonamide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Chloro-N-[(4-methyl-5-{[(4-nitrophenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methyl]benzene-1-sulfonamide (CAS 338421-52-6), a certified reference material (molecular formula C17H16ClN5O4S2, MW 453.92 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-N-[(4-methyl-5-{[(4-nitrophenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methyl]benzene-1-sulfonamide (C17H16ClN5O4S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 4-Chloro-N-[(4-methyl-5-{[(4-nitrophenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methyl]benzene-1-sulfonamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
